Wrong character shown for alt 8369 in anything but notepad

I had a problem with the peso character showing on my system, I installed then reinstalled the Philippine character codes and now it shows as it should so all is correct, the character exists as it should.

If I hold the alt key and input 8369 in notepad I see the correct character the ₱ sign, if I open notepad++ or type it in the search bar in my browser I see this character.
Does anyone know why this happens and how I can fix this annoying problem (or the alt code to use) as now I have to find and copy and paste the key from elsewhere instead of just inputting it easily as I should be able to.
